Architecture

The GX5731 is a 6U PXI board that provides 224 digital Inputs or Outputs arranged in seven 32-bit ports. Four of the ports provide 128 TTL levels and can be programmed for Input or Output in groups of 8. The other three ports require GX57xx I/O modules that provide customized levels, handshaking, and on-board memory. The GX57xx expand the I/O capability of the GX5731 to 224 Input or Output channels.

The GX5731 can accommodate up to three I/O modules to achieve custom I/O levels and functions. I/O modules provide between 16 and 32 channels and some offer onboard memory for vector I/O. Available I/O modules include:

GX5701: DIGITAL INPUT LATCH (DIL)

This module provides 32 Input channels with programmable threshold (-12V to +12V), handshaking for synchronization, and 4K vector memory. The GX5701 is compatible with the obsolete Summation DIL card.

GX5702: DIGITAL OUTPUT LATCH (DOL)

This module provides 32 TTL Output channels, handshaking for synchronization, and 4K vector memory. The GX5702 is compatible with the obsolete Summation DOL card.

GX5703: LVDS TO TTL (LTT)

This module provides 32 LVDS Input channels, handshaking for synchronization, and 4K vector memory. TTL.

GX5704: DIGITAL POWER OUTPUT LATCH (DPO)

This module provides 32 Open-Collector Outputs capable of driving signals up to 50V with 500mA current sink, handshaking for synchronization, and 4K vector memory. The GX5704 is compatible with the obsolete Summation DPO card.

GX5705: RS-232 TO TTL (RTT)

This module provides 32 RS-232 levels inputs that are converted by the module to TTL.

GX5709: DIFFERENTIAL DIGITAL I/O

This module provides 32 RS-422 differential I/O Channels. Direction is programmable in groups of eight.

GX5710: LVDS DIFFERENTIAL DIGITAL I/O

This module provides 32 LVDS differential I/O Channels. Direction is programmable in groups of eight.

GX5711: LVDS TO TTL (LTT16)

This bi-directional I/O module converts 16 differential LVDS inputs to TTL outputs or 16 TTL inputs to 16 differential LVDS outputs.

GX5712: RS-422 TO TTL (RTT16)

This bi-directional I/O module converts 16 differential RS- 422 inputs to TTL outputs or 16 TTL inputs to 16 differential RS-422 outputs.

The GX5731 and GX57xx I/O Modules are supplied with a software package that includes a virtual panel stand-alone application, driver, and on-line documentation. The virtual panel can be used to interactively control the instrument from a window that displays the current instrument settings and allows you to control and change them.

The driver is a library of functions that is used to control and change the instrument settings from within your application. The instrument driver is provided for Windows operating system (32 bit DLL). In addition to the driver library, various interface files provide access to the library from your favorite programming tools and languages. These interface files support programming from ATEasy, Microsoft and Borland C/C++, Microsoft Visual Basic, Borland Delphi and more.
